When I an slowing over coarse pavement or loose gravel I feel a strange feeling in the brake pedal. I think it have to do with the anti-lock system. Is it normal?

 

If it feels like a vibrating or pulsing feeling, it's the ABS kicking in...the car brakes the wheels and, since you're on a surface with very little traction (friction), the wheels lock up. The ABS sees this and tries to remedy it. You'll of course get the same thing happening on ice and other slick surfaces.

So, if it's that, it's totally normal.

 

Thanks!

 

It might be your VSA kicking in too.

 

I believe the VSA uses the ABS to control the car...it also controls throttle, which you'd not feel through the brake pedal (you'd see it on the tach, though).

 

I spoke to the Acura dealer becasue I was complaining of the same problem only that in Montreal...road conditions are hurendous i mean pot holes like every 2 ft..there isnt one stretch of smooth surface excelt the highway....nyhow on bumpy streets when I would come to a complete stop....the pedal would push back and the abs came on..its totally normallll..tire pressure shuld always be adjusted......

 

The ABS are quick to activate...
